Break out the write logic into a separate function and simply use it as
a callback to glob_item.
This allows users to consolidate writes to sysfs with multiple similar
pathnames, e.g.
w /sys/class/block/sd[a-z]/queue/read_ahead_kb - - - - 1024

The kernel implicitly does sync() anyway, hence there is no need to do
that in userspace explicitly. This makes the "-n" switch to halt(8) a
noop.

This splits the JSON output mode into different modes: json and
json-pretty. The former printing one entry per line, the latter showing
JSON objects nicely indented and in multiple lines to make it easier to
read for humans.

After talking to the cgroup kernel folks at LPC we came to the
conclusion that it is probably a good idea to mount all CPU related
resp. all network related cgroup controllers together, both because they
are good defaults for admins and because this might prepare
for eventual kernel cleanups where the ability to mount them separately
is removed.

SuccessExitStatus= a bit
|
|
In some cases, like wrong configuration, restarting after error
does not help, so administrator can specify statuses by RestartPreventExitStatus
which will not cause restart of a service.
Sometimes you have non-standart exit status, so this can be specified
by SuccessfulExitStatus.

- don't use pivot_root() anymore, just reuse root hierarchy
- first create all mounts, then mark them read-only so that we get the
right behaviour when people want writable mounts inside of
read-only mounts
- don't pass invalid combinations of MS_ constants to the kernel

Makes possible to specify separate timeout for start and stop of
the service.
[ Improved the manpage. Coding style fix. -- michich ]

This is useful e.g. if the keyfile is a raw device, where only parts of it
should be read. It is typically used whenever the keyfile-offset= option is
specified.

We want to keep things uniform, and hence treat udevd's man page like
any other in the repo. What matters is how users primarily interface
with a service, and that is not the binary path in /usr/lib/systemd but
the service name.
This reverts commit 6c1f3ba54ac1f42598c543b86daaf294b29294b1.

Instead of making systemd-udevd a so-link to systemd-udevd.service,
ship the real page as systemd-udevd to integrate better with distros
where udevd might be run standalone.

This should address TODO item "new dependency type to "group" services
in a target". Semantic of new dependency is as follows. Once configured
it creates dependency which will cause that all dependent units get
stopped if unit they all depend on is stopped or restarted. Usual use
case would be configuring PartOf=some.target in template unit file
and WantedBy=some.target in [Install] section and enabling desired
number of instances. In this case starting one instance won't pull in
target but stopping or starting target(in case of WantedBy is properly
configured) will cause stop/start of all instances.

systemd --version mirrors systemctl --version:
$ ./systemd --version
systemd 186
other
+PAM +LIBWRAP +AUDIT +SELINUX +IMA +SYSVINIT -LIBCRYPTSETUP
This information can be retrieved by other means (systemctl, etc.),
but it's easier for a newbie if 'systemd --version' says something
useful. And 'systemd --help' is already there, so let's complement
that with '--version'.

Previously, when the main data hash table grows too full the performance
simply started to decrease drastically. Instead, now simply rotate to a
new journal file as the hash table gets to full, so that we can start
with a new fresh empty hash table.

Make sure the man page titles are similar in style and capitalization so
that our man page index looks pretty.

These printf specifiers allow us to refer to $HOME and $USER
in unit files. These are particularly helpful in instanced
units that have "User=" set, and in systemd --user domains.
The specifiers will return the pw_name and pw_dir fields
if the unit file has a User= field.
If the unit file does not have a User= field, the value
substituted is either $USER or $HOME from the environment,
or, if unset, the values from pw_name or pw_dir.
This patch is somewhat after Ran Benita's original patch,
which didn't get merged. I've split up the 2 specifiers
and extended them to do what is logically expected from
these specifiers.
Note that expansion is done at `start` time, not after
the units are parsed. Using `systemctl show` will just
show the specifiers.
